Abstract: In accordance with the present invention, a modular clean room plenum is provided. This modular clean room plenum includes a rectangular plenum body with an air barrier forming a top surface of the modular clean room plenum and a ceiling grid forming a bottom surface of the modular clean room plenum. The modular clean room plenums are attached to the primary support structure of a clean room building in whatever number and configuration is required by the clean room layout. By providing, in one modular component, the air barrier layer, the ceiling grid, the framework between the two layers, the fire sprinkler system, the air transfer ducts, the balancing dampers and all of the normal components of the ceiling grid, the cost and time required for construction can be significantly decreased.
